Post subject:  LIst of changes over life of Islands

I think it would be useful to have a comprehensive list of all the changes that Hobie made over the years to the Adventure Island and Tandem Adventure Island, and when. This would be useful to someone who wanted to see what had changed since the boat he/she owned, or was considering buying, was made. It would make sense, once the list was compiled, to place it in the FAQ area. I have communicated with Matt about this, he likes the idea, but doesn't have time, or even the records, to compile it.
I figured the collective experience of the people in these forums could probably come pretty close to a complete list of what has been modified.
I am far from expert on this myself. I have a 2008 AI and a 2010 TI, and know some of what has changed since then on these boats, though not always an accurate idea when. However, to get things started, I am posting a list of things I could think of, and I will compile any additions or corrections to this that appear in this thread, and present it to Matt for checking and posting when it seems fairly complete.
For any item, it would be good to know when it went into production, what it is, and whether it can be retrofit to older boats. Please follow the same format, with two dashes between fields (--) to make it easier to compile.
Thanks for your help.

A couple things for you to add to your list:

2012 - scupper reinforcements for AI. This was a running change though so not all 2012 kayaks will have them.

Click n go MirageDrive attachments came out for the 2009 model.

May 2007 - Balanced Rudder change for AI

new aka hinges - 2011 model

TI introduced Spring of 2010 for the 2011 model year.

MirageDrive guide tracks - 2012 model year.

Inflatable Lumbar - 2010 model I believe
expandable seat pegs 2010 model year

V1 plastic sprockets - 2005 model year
v1 plastic drums - 2003 model year (I think)
V2 drum shaft - 2009 model year
V2 sprockets/masts - 2009 model year
V2 drums/cables - Spring 2008, before 2009 model year

My 2012 TI doesn't have scupper reinforcements.

BCastile--my 2011 AI seat does not have the inflatable lumbar support.

Thanks for the input to the list. I was beginning to think no-one had any interest in this project.
I have and will represent changes that appeared in some of the boats of a model year as half-years. E.G. 2011.5 will mean boats from late 2011 have it, early 2011 don't, but I won't try to figure out just when in the year (or serial number, which would be ideal) it happened.

I hope that Hobie will start to keep records at the level of detail that would include date and serial number of both tweaks and major changes. I, for one, am willing retrofit my boats with such things as, for example, stronger socket bolts when experience shows they are needed, and Hobie updates them and makes them available.

I am thinking that reposting the whole list from time to time, rather than editing my initial post, which subsequent posts corrected, makes the most sense. Any feedback?
If noone points out why that is a bad idea, I will post a new list soon, with the above updates and others I have learned about.

I will also include part numbers when the retrofit is accomplished by a part

Great effort! You can bet there are any of us grateful for the list you are compiling

Post subject:  Re: LIst of changes over life of Islands

The scupper changes were made over a few months. It required pulling the mold out of production for some time. Since we have a lot of molds to update, and always other maintanance projects going on, something like this had to be a running change and not all done for the model year.

Chekika - Thank you for pointing that out about your seat. I thought those seats had been out longer than they have I guess.

We have records of the changes with serial numbers. It's not compiled into a list like this so they can take some research to find. If there is something you are curious to know, and can't find on the forums, send me an email or PM. Just don't ask for a list of all changes for a certain model for its entire history!

OK, I'll take "Useless Hobie Trivia" for $1000, Alex. ;-)

I offer these for your list, in rough order of appearance. Others can fill in the blanks and pinpoint the years. If I missed anything, our jeopardy master KBob can chime in with it.

Beebrain, since you brought it up, we'll let you organize these braindumps by product and year. I just hope we are not duplicating the work done by MadMax.

Thanks for the additions, and the attitude. I don't know of MadMax's work, and can only find one post by him on the forums. I also hope I am not duplicating...

Post subject:  Re: LIst of changes over life of Islands

what is:

1.5" TI tramp webbing
& spine w/surge block, molded alignment pin?

gonna do some research on my own now but thought i would ask since i doubt i will find much out on the outroweb. thanks,

Post subject:  Re: LIst of changes over life of Islands

Visiting the Hobie factory in February, I saw a stack of new Mirage Drives. They have a spine which incorporates a plastic pin to fit in the alignment slot on newer kayaks, (replacing a metal pin in recent mirage drives, they would have to be cut off to fit older boats), and the spine also had a shape which made it a better plug for the drive well, making the rubber seals that were available to reduce surge from the drives (or from sailing) unneeded, and, I expect, doing a better job than they did. I was told that they could be retrofit to existing drives. I do not know of a special part number for them, it may be same number as the prior spine. Perhaps Matt will enlighten us.

I also read on the forums that 2013 TI's had wider webbing and webbing buckles than older boats, presumably stronger, though I have not seen this myself. I don't know if they are any easier to get tight.

I'm really interested in this as there's a 2009 AI on sale near us at the moment.

How significant are any of these changes? Do they fix major shortcomings with the previous design?

Also, are there any other issues with older boats that buyers should be aware of?


Author:  beebrain [ Mon Apr 15, 2013 1:46 pm ]
Post subject:  Re: LIst of changes over life of Islands

Good, that is exactly why I created the list!
Things I would say are pretty significant (opinions may vary):
Click in drives are handier and maybe stronger
Tilt up rudder is way more authoritative, but many find twist and stow adequate for AI
I upgraded my seatposts, the twist locks are much handier, and more secure.
corrosion problems on salt water likely to be less on crossbar of clipped V2 akas than pinned ones (alu/ss galvanic corrosion issues), probably not an issue for fresh water only
rudder up/down kit should be on 2009, but if not count on doing it.

Other things are nice, but not worth considering a new vs used boat for, in my opinion.

Post subject:  Re: LIst of changes over life of Islands

Anyone know if this list was transferred somewhere else and kept evergreen?

When was the Vantage Seat introduced?

When did the hull/ama displacement increase?

I'm considering buying a 2013, anything in that model year I need to know about?
